ChatVault
EN·中
For people who use ChatGPT, Claude, Gemini, and DeepSeek — sometimes all at once.

A quiet library
for every conversation
you have with the machines.

ChatVault captures every chat, makes them searchable across platforms, links them, and gives back the prompts you keep losing. Today, it lives entirely on your laptop.

Postgres index strategy for time-series writes

You asked
How should I index this table? Append-mostly, ~50k inserts/min, queries are time-bucketed.
Claude
For 50k inserts/min on append-mostly tables, BRIN over a (created_at) column outperforms btree by a wide margin both in write throughput and on-disk size. The tradeoff is range-query selectivity — BRIN works well when rows correlate with their physical order…

What about clustering?

The problem

"I remember talking to AI about this — but I can't find it."

ChatGPT only searches titles. Claude has no search at all. Gemini chats vanish into Google Drive. The good prompts you wrote last month are scattered across four tabs, and none of them talk to each other.

"One morning the account is gone — and the chats are gone with it."

Accounts get suspended. Plans get downgraded. A platform pivots, a region gets cut off, a tab is closed by accident. Months of conversation can disappear overnight, because they only ever lived on someone else's server. With ChatVault, a copy is already sitting on your laptop before any of that happens.

Six small tools that do one big thing.

Bring every AI chat under one roof, then organize it like the rest of your knowledge.
